.To all vif/'wm :it may concern:

Be it known that I, PAUL l?. il/ C. lliure- Pnanour, a citizen olf the United States, residing at Lynn, in the county of Esser and State oi lli/laissachusctts` have invented cer tain improvements in hoes, of which the following description, .in connection with the accompanying drawings, is a specification? like reference characters on the drawings incheating` lilie parts in the several figures. n This invention relates to shoes and is heren in illustrated as embodied a shoe of the welt type although it will he understood that the invention can also he embodied to advantage in shoes of other types.

In the present standard ready-made shoes practically no attempt is made to provide for the arched formation of the shank porn tion of the :toot and particularly for the transverse arch ot the foot. Consequently these shoes, hy :failure to provide uniform support throughout the shank: portion ot' the foot., cause niore or less unnatural developnient and unbalanced muscular condition of the toot since the normal strain on the various muscles ot the foot which should he distributed over a large portion of the foot, a relatively small part of the foot, and. in many instances, such shoes are directly responsible t'or broken arches and other foot maladies. Many expediente have heen adopted for the purpose ot' correcting this detect., the most common being to incorporate in the shoes mechanical appliances or artificial supports such as metal plates. These corrective supports, however, have in general proved unsatisfactory and only increase the cost ot' the shoe and add unnecessary weight to the shoe. Moreover, arch supports render shoes eX- ceedingly stiilfandintieizihle and often restrict the norihal functions of the various toot muscles in such manner as to make the wearing of the supports perm inentlv necessary instead of acting after a short temporary use thereof to relieve the strained condition oi the feet sufficiently to permit normal de velopment ot the foot muscles and any t'urther wear of the support unnecessary.

The present invention aims to provide an' proi'fcd shoe which will contorni more actaately to the anatomical structiro ot the foot and otlor better support for the shank portion ot. the foot than ready/inode shoes as .heretofore constructed while? at the saaie peelllcation or Letters luttent.

time, allowing for. the natural and proper development of the muscles of the foot; and which furthermore, can he produced without materially increasing the cost of the shoe or dctracting from its appearance.

lilith these objects in view the present invention, in one otits aspects, comprises a novel shoe sole characterized by a shank portion which is so formed as to correspond substantially to the arched conformation of the shank portion of the foot and which is treated to maintain permanently the conformed condition ot' the sole. In the illustrated embodiment o1"- the invention, the desired arch of the solo in the shank is produced by buckling the shank portion of the sole upwardly and locking the buckled portion of the sole in such manner as to allow considerable ilexibility ot' the shoe in the shank whereby thc natural development oi' the foot muscles are not restricted while at the same timcadeouate and uniform support is provided throughout the entire shank portion of the toot.

In another of its aspects. the present invention contemplates providing a novel shoe in which the shank portion ot the sole of the shoe is formed to correspond substantially to the arched conformation of the foot and the shoe upper is cut'in accordance with the particular formation of the sole to assist the solo in supportingr the foot and to obtain a close :fitting shank for the shoe.

Other objects and features of the invention will be apparent when the following de scription and claims are considered in connection with'the accompanying drawings 1n which,--

Figure 'l is a perspective view ot the heel portion of a shoe constructed in accordance with the present invention;

Fig. 2 is a side elevation of the insole;

Fig. 3 is an inverted plan view 0l the insole; and i Fig. 4 is a plan view of the outsole.

r he preferred method of making' one form ot' the shoe constituting.,r the present invention is disclosed and fully described in my co-pe'nding application Serial No. 102.447, sied June s. 1916.

Referring to the drawings the shoe illus trated is of the welt typo alrd comprises` an upper 2, an insole 4, an outsole 46 and a heel ll. The last upon which the shoe is made .is similar to an ordinary commercial Ill@ last except that the shank portion of the last is srmewhat deeper particulartv at the inside shank and correspondsl more closely to the contour of a normal foot.

The insole t may be ol the type ordinarily used in making a (ioodvear welt shoe ant i5 therefore. provided with the usual stitch receiving channel l0 en its under face. the channel extending from the heel breast line at one side of the insole. about the forepart thereof, and terminating at the heel breast line at the opposite side of the insole. Preferably` also the insole is provided with an additional area ol' stock 12 along its inside Shank for the purpose' of offering greater support to the inside shank portion of the foot' when the, insole is. incorporated in the shoe and also reducing the tendency of the foot to roll inwardly in the slice.

ln accordance with the present invention the shank portion of the insole 4 is conformed to the lateral and transverse conformation of the shank portion of the foot and. as herein shown. this is accomplished bv buckling the stock in the shank portion of the insole upwardly to form an arch eor responding substantially to the arched conformation of the shank portion of the foot it is to Support. The illustrated preferred manner of buckling the stock in the shank of the insole is to separate the heel end of the insole into inside and outside portions 14 and 16, respectively. and displacing or offsetting the inside portion 1t laterally in the direction ot' the arrow. Fig. 3. into such position as will create a fullness of stoek along the inside shank portion of the insole and form an arch 18 of such curvature as to correspond to the arch of the foot it, is desired to support. Preferably the heel-end of the sole is separated by a buttonhole cut 20 which extends approximately centrally of the heel end of the insole from the heel breast line to its rear edge. The amount of fullness created in the shank portion of the insole and the formation of the arch 18 depends to a large extent upon the location of this cut and it has been found in practice to be preferable to locate the perforation 22 of the cut approximately central of either side of the insole at the breast line in which event the outside shank portion of the insole is notI affected by the buckling of the material at the inside shank thereby providing a substantially level surface for the outside. shank portion of the foot. ln order to confine the buckled portion 18 of the insole to the inside shank and to cause the stock to arch progressively from the substantially flat outside shank portion of the insole,'it has been found advantageous to score the under side of the insole as indicated at Q4. The buckled portion 18 0f the insole is preferably maintained in its conformed condition by a V-shaped locking wedge 2G located between the inside and the outside portions 14 and 1G of the heel end of the insole 4, the locking member :2G being of sutticient size and shape as to prevent the inside portion 14 and the buckled portion of the sole from returning to its normal position. This wedge 26 is held in position between the inside and outside portions 14 and 16 by otlsets '28 projecting into cooperating notches 80 in the inside and outside portions of the insole. Staples 82 may also be inserted as indicated in Fig. 3. In consequence of this construction it will be noted that thev arch 18 provided iny thevshank o insole is substantially the same as the arched conformation of the foot, that is, the arch of the insole is progressively curved upwardly from the outside shank to the inside shank so as to conform to the transverse eont'ormatlmi of the foot and at the same time a longitudinally disposed arched formation 34 (sce Fig. 2) is also created which formation increases progressively in height from the outside shank to the inside shank as does the corresponding formation of the foot. Also it will be noted that the arch 18 of the insole is permanently locked or maintained in arched position entirely independently of any means cooperating directlywith the arched portion ot' the insole whereby it is entirely free to yield and conform itself to the movements and changes of the arched conformation of the shank of the foot during wear. 'A

The upper 2 may be cut substantially the same as the ordinary upper except that the portion 36 of the upper along the inside shank where it is secured to the arched portion 18 of the insole is cut away to compensate for the arch 18 and'to enable the upper to be drawn in close at the shank and to provide additional support for the inside shank ortion of the foot. The upper 2 and a Welt 38 are-secured to the insole 4 by stitches 40 received in the channel 10 in the usual manner. The -shoe is provided with the usual filler 42 and if desiredl a shank piece 4-1 may also be utilized although the peculiar arched formation 18 of the insole ie the shank will ordinarily be found sufficien. to maintain the longitudinal curvature of the shoe in the shank.

The outsole blank 46 of the shoe is of the usual construction and is also buckled along its inside shank in a similar manner to the insole to provide an arch 48 which will conform tothe arch 18 of the insole and operate to reinforce said arch. The buckled portion 48 of the outsole is preferably produced in the same manner as that of the insole by separating,r the heel end of the outsole into inside and outside members 50 and 52, rc-

the

spectively, by a buttonhole cut 54 extending from approximately the heel breast line of .tion 18 and outside similar proportions to' the jarched formaof the insole. The position of the inside member of the outsole, after the desired amount of buckling has been obtained in the shank,is maintained by a similar wedgeshaped locking member 56 located between the ott'set portion 50 and the outside nortion 52 of the sole 46, the locking memer being retained in position by offsets 58 interlocking ivith notches 60 in the inside portions and by staples 6:2 as in the insole 4. By forming an arch 48 in the shank of the outsole 4G adapted to lit in under the the insole it will be seen that the insole flexing of the shoe during wear is relieved.

i lso it will be noted that by locking both insole and outsole in their conformed condition there is no tendency of the soles to return to their normal condition thus relieving the strain of the upper materials across the instep of the foot. The outsole J-G 'is secured to the welt 8 attached to the heel 8 covering the portion o f the out- Preferably the arched sole 4G is conlined entirely tion thereof so seat is provided to receive the heel.

to the shank porshoe constructed in the manner above` anatomical structure of the foot throughout both the loneidescribed conforms to the b3 -tudinal and transverse c urvatures of the foot 1n the shank so that the weight of the body is distributed uniformly over those parts of thofoot that are designed to sustainthis weight. Moreover, the shoes are exceedingly-flexible and maintain a proper'disposition of tho l'oot; in the shoe lso that the,

y normal functions of the various muscles of the foot are not interfered'-with. noted further' that e ,50
